Title: Improvements in liquid supply systems
IPC: F02B1/00
Filed: 1925-05-06
Abstract: 248,957. Marks, E. C. R., (Remington Manufacturing Co., Inc.). May 6, 1925. Direct air pressure apparatus.-A system for raising liquid fuel from a low-level tank for feeding a carburettor comprises a suction or pumping chamber 10, Fig. 2, connected by a pipe 6 to a cylinder and piston for producing alternate pressure and suction, by a valveless pipe 3 to the fuel tank, and by a conduit 30, check valve 33, chamber 11, and pipe 4 to the carburettor, the resistance to backflow through the pipe 3 being greater than the minimum resistance to outflow through the conduit 30. The fuel enters the chamber 10 through a stand pipe 22 having apertures 23 surrounded by a cap 27 and a filtering screen 25. When the carburettor has been filled, further action of the device causes an accumulation of air pressure in the chamber 11 to balance the pressure impulses in the chamber 10, the fuel then surging idly in the pipes 3, 22 to and from the chamber 10. In a modification, Fig. 4, the impulses are produced by a cam-actuated piston 52 in a cylinder 43 above the chambers 45, 46, the cylinder being closed by a head 50 having a shank 51. The fuel inlet to the chamber 45 is controlled by a ball valve 68 carried by a float 70 and the outlets to the chamber 46 by a disc valve 73, the chamber 46 being connected at 77 to the carburettor. The valve 68 is initially in contact with the lower seat 65, so that it acts as a non-return inlet valve until sufficient fuel is drawn into the chamber 45 to lift the float 70. When the fuel reaches normal level, the valve 68 is lifted from its seat and the inlet conduit is uncontrolled, as in the first form described above. If the fuel level rises further, e.g. on an incline, the float brings the valve 68 into engagement with an upper seat, closing the inlet until the fuel level returns to normal, and so preventing accumulation of fuel and access of fuel to the chamber 44. In order to alter the capacity of the chamber 44, the plug 51 may have an axial cavity closed by an end cap and connected to the air space in the chamber by a small hole in the wall of the cavity.

[Also in Divisions B8, E2 and F2] An adjustable length link, e.g. the support pillar of a chair, comprises a hollow plunger 13 slidable in a cylinder 10 and constituting a liquid reservoir which is pressurised by a flexible sac 46 of compressed air, and a rotary valve 36 to open and close a connection 44, 45 between the reservoir and the cylinder so that on opening the valve, liquid under pressure is admitted to the cylinder to force the plunger axially, and on closing the valve, liquid is trapped in the cylinder to prevent movement of the plunger in one direction. The ends of the plunger 13 are swaged into annular grooves 32, 28 in closing plugs 14, 27 of plastics material, a plastics piston 31 being snap-fitted into a groove 29 of the plug 27. The cylinder ends are swaged on to closing plugs 17, 21 of plastics material and distance tubes 23, 24 and sealing rings 25, 26 limit the piston travel. The link shown is lockable against compression loads. By connecting the reservoir to the other side of the piston a link lockable against tension loads is formed.

Abstract: 1,156,899. Electric digital calculators. PHOTO MAGNETIC SYSTEMS Inc. 13 March, 1968, No. 12257/68. Heading G4A. [Also in Division H4] A computer system includes a frequency response computer and a tone generating telephone set connected to the computer, the set having a plurality of keys operative when actuated individually to produce first signals having different frequency characteristics corresponding to the key actuated and operative when actuated in groups to produce second signals having still different frequency characteristics corresponding to the group of keys actuated, the computer being responsive to the signals to receive data and be commanded in accordance with the signals. A push-button telephone set having buttons as shown in Fig. 3 has different frequencies associated with each row and column, i.e. #1-#7 as shown in Fig. 3. Each button pressed singly produces two frequencies corresponding to its row and column placement. For instance 1 produces f1 and f5, 8 produces f3, f6 &c. However if two buttons are pressed simultaneously only one frequency, the common frequency, is produced, e.g. if 2 and 3 are pressed f1 is produced, if 4 and 7 are pressed f5 is produced. These signals can be distinguished by the computer so that the former are recognized as digits and the latter as instructions, the frequencies being translated to digital pulses at the computer.

Abstract: 781,579. Actuation of switches. ENGLISH ELECTRIC CO., Ltd. April 29, 1955 [April 30, 1954], No. 12690/54. Class 38 (5). An interlocking mechanism has two members 11, each of which may occupy a position A or a position B, but which may not simultaneously occupy positions A, the interlock comprising a plate 10 slidable between positions in which an aperture therein is adjacent one or other of the members 11, each of which has a part which may extend through the aperture when the member occupies position A, and is capable of movement to position B when the aperture is adjacent the member. There may be four members 11, pivotable about shaft 12, only one of which can occupy position A at any time. The members 11 may be so shaped (Fig. 1b) that when in position A a part thereof extends through the aperture and prevents the plate 10 from moving to expose any of the other members, all of which are thus locked in position B by the plate. The aperture may have a cutaway portion to engage and lock the protruding part of a member 11 in position A. The plate 10 may have more than one aperture separated by a distance which is not equal to the distance between members 11 and arranged so as to give access to only one member 11 at a time. In an alternative arrangement (Fig. 4) a plate 13 provided with a slot 14 and a keyhole 15 is slidable in a frame 16. Two rows of push-rods 17a, 17b are slidable in bushings 16b, and support arms 16c carry spindle 18 on which a T-shaped lever 19 is pivoted. Contacts 20 are arranged adjacent the foot of the T and the ends of the arms of the T are connected to the push-rods so that when 17a is depressed, 17b is raised. All the push rods 17b extend through slot 14, but only one rod 17a can extend through hole 15, thus only one pair of contacts 20 can be open at a time. The rods 17a may have necks 17c by which they can be locked in keyway 15a. Switchgear actuating members 30 (Fig. 6) pivotally mounted on a spindle 31 have their A and B positions determined by stops 40, 41. The member 30 shown is locked by the sliding plate 42 in position B. When all members 30 are locked, contacts 44, 45 are closed and may complete the tripping circuit of an oil circuit-breaker. The plate 42 cannot be moved unless shaft 51 is turned to disengage fixture 52 from member 63, and this shaft cannot turn unless it is pressed inwardly against a head 50 to open contacts 44, 45 and disengage pin 53 from a hole 43a in front cover 43. When shaft 51 is turned, pin 53 engages a slot in plate 42, causing the plate to slide and expose an actuating member 30 which may then be moved to position A. Specification 779,354 is referred to.
